you have to remember they use motor current as a sensor. as the motor ages and bearing get loose the rotor will start to contact the stator walls. this causes friction and increases current which throws off the board
there is no water level sensor in this machine so they use the motor to make sure there is enough water flow to turn on the heater. if bars are blocked, water diverter is stuck or the motor current is not correct it wont heat
makes life a lot more difficult

I don’t think it’s the motor because I can hear it running and the water is getting distributed by the arms.
just had a job like that motor runs and no heat
change motor and it heats again
heater was not open circuit so its was not the heater that was at fault
problem is the use the motor as a sensor to detect water flow

try contacting
https://www.qualityelectronicrepairs.co.uk/
to see if it can be fixed
the board is simple to remove and you could post it off
Dave
well the first check with those symptoms is the board
does sound like the power supply on the board may have gone
Dave
no heating can be various things
heater
motor
boardthats the problem working out which
heater can be tested the rest is guess work
Dave
well the relay wont be the cause its just the thing thats making a noise
was hoping it was a capaciitor fault but they look ok
it also may not be this board

try contacting here and see if it can be repaired or tested
Dave
since the machie is capable of 2 heats there are 2 relays controlling the element
on delicate fabrics only one element is energised but on cottons both are active
Dave
as far as i can see its no longer available
what is wrong with your board ?
and which board is faulty ?
